it might be interesting if you could share the details to grow the
shared knowledge and experience in case there are some instances of
these problems reported in the future.

In particular, it'd be interesting to hear:

- hypervisor

- VM OS + if plain oblivious to running virtualized,
  or "the optimal arrangement" (e.g., specialized drivers, virtio,
  "guest additions", etc.)

(I think IPaddr2 is iproute2-only, hence in turn, VM OS must be Linux)

Of course, there might be more specific things to look at if anyone
here is an expert with particular hypervisor technology and the way
the networking works with it (no, not me at all).
